How to change the width of the Main Menu

Hi,

You could try a code like the one below for example. It will make the header look like this

And also the header when sticky will look like this (this can be removed if you don’t want it – the last part of the code)

Enter it in Theme panel->Custom CSS

.td-header-style-5 .td-header-menu-wrap-full {
background-color: transparent;
}
.td-header-style-5 .td-header-main-menu {
background-color: #1e73be;
}
.td-header-style-5 .td-header-menu-wrap.td-affix {
background-color: transparent;
}

Thanks
